Frost attended St. John's Episcopal School and was salutatorian at Trabuco Hills High. She was 22 and had just graduated as valedictorian from Boston University when she perished during the attacks. The daughter of Tom and Melanie Frost, Lisa was returning home on United Airlines Flight 175, but the airliner was hijacked and flown into the south tower of the World Trade Center. It was the second jet to hit the towers that morning.
The memorial was dedicated on Dec. 21, 2001 on what would have been Frost's 23rd birthday.
The memorial includes a Trabuco Oak enveloped by Pentagon-shaped wrought iron that includes two spirals on the corners closest to the memorial. The spirals represent the World Trade Center buildings, the fencing represents the Pentagon, which was also attacked during the 9/11 attacks, and the Trabuco Oak represents rural Pennsylvania in which United Flight 93 crashed after passengers overtook hijackers.
